Synthesis of Aminopyridazines from Azidopyridazines and Tetrazolopyridazines
Kappe, Th.,Pfaffenschlager, A.,Stadlbauer, W.
, p. 666 - 671 (2007/10/02)
Azidopyridazines 3, 4, 24 and tetrazolopyridazines 10, 13, 28 can be converted to the corresponding aminopyridazines, by reaction with triphenylphosphine via phosphazenes and subsequent hydrolysis (Staudinger reaction).
